SetOptions for CoordinatesToolOptions for DateListPlot?@Mr.Wizard Use SetOptions[ DateListPlot, PlotLegends -> Automatic] then simply plot two TimeSeries by DateListPlot[TimeSeries @@@ {{{1, 2, 3}, {1}}, {{3, 4, 5}, {1}}}]. Result: No legends, but if you add the options directly they will be plotted.

Dataset vs an association of associations+1. Very helpful answer that seems to explain why I do have trouble putting TimeSeries and EventSeries in Dataset. It seems to work but I do get interpretation warnings and the Objects are displayed with a red frame. Maybe better to put the information in a List then apply the needed Head after extraction?

Dataset vs an association of associationsI am not sure about internal intricacies and performance aspects but the Dataset to me simply is a generalization of what can be built using List and Association: You can have a Dataset to be a List of Lists or an Association of Associations - that kind of flexibility is absent with Association. So I use Dataset whenever I think of a complete set of data (eg. like a database), while Association is a building block and thus on a slightly lower level of abstraction.

Is FrameTicks broken in 10.1.0?I would say that rcollyer has provided a convincing argumentation -- somtimes "things change" and we simple humans have to adapt and break with dear habits. ;-) In any case I would suggest to remove the bug tag because Mathematica does behave according to its current documentation.
